OK, now that some seroprevalence survey results are finally available (even though they are at least two months out of date (and not really accurately applicable to current up to date Covid-19 tracking) I'll display how to use them anyway.

New York (note Metro area not necessarily same as state)

total cases = 422,268 total deaths= 32,248 4/01/2020 seroprevalence survey adjustment 12X higher AdjTotCases = 5,067,216 cases

32.248 deaths / 5,067,216 = CFR (case Fatality Rate) 0.63%

Connecticut

total cases = 46,717 total deaths= 4,335 5/03/2020 seroprevalence survey adjustment 6X higher AdjTotCases = 280,302 cases

4,335 deaths / 280,302 = CFR (case Fatality Rate) 1.54%

Western Washington State (note western area not necessarily same as state)

total cases = 36708 total deaths= 1,359 4/01/2020 seroprevalence survey adjustment 11X higher AdjTotCases = 403,788 cases

1,359 deaths / 403,788 = CFR (case Fatality Rate) 0.33%

South Florida (note South Florida not necessarily same as state)

total cases = 200,111 total deaths= 3,732 4/10/2020 seroprevalence survey adjustment 11X higher AdjTotCases = 2,201,221 cases

3,732 deaths / 280,302 = CFR (case Fatality Rate) 0.16%

Missouri

total cases = 24,444 total deaths= 1,074 4/26/2020 seroprevalence survey adjustment 24X higher AdjTotCases = 586,656 cases

1,074 deaths / 586,656 = CFR (case Fatality Rate) 0.18%

Utah

total cases =24,952 total deaths= 184 5/03/2020 seroprevalence survey adjustment 11X higher AdjTotCases = 274,472 cases

184 deaths / 274,472 = CFR (case Fatality Rate) 0.07%
